Abstract

The invention discloses an AND logic gate and an NAND logic gate based on magnetic skyrmion. The magnetic skyrmion is placed in the annular magnetic racing track. A voltage driving mode is adopted toenable the skyrmion to circularly move in the magnetic racing track, and the state of the skyrmion in the magnetic racing track is read through the magnetic tunnel junction, so that the logic functions of the AND gate and the NAND gate are realized, and the stability of the NOT gate based on the skyrmion and the AND gate in use is ensured.

Description

technical field

[0001] The invention relates to the field of logic devices, in particular to an AND logic gate and a NAND logic gate based on magnetic skyrmions. Background technique

[0002] AND logic gates and NAND logic gates are relatively common devices in logic devices, and are an indispensable component in digital circuits. Traditional logic devices are generally prepared by CMOS technology. With the improvement of device integration, this The defects of this kind of semiconductor technology are gradually exposed: on the one hand, the leakage current of the transistor increases with the decrease of the size, and the power consumption of the device gradually increases; very difficult.

[0003] Magnetic skyrmions are a magnetic structure with topological protection properties in magnetic materials. Due to their nanometer size (the smallest diameter is only a few nanometers) and topological protection (good stability), magnetic skyrmions are highly integrated The infor...
